104 MR. E. W. BINNEY ON THE PERMIAN BEDS 



like the conglomerates of Cheetham weirhole and Patricroft ; 

 and I am, therefore, inclined to class them as such. They 

 are, I believe, as stated in my former paper, at page 266, 

 often unconformable to the underlying lower new red sand- 

 stone upon which they rest. 



The clay, with beds of shale, 30 feet in thickness, was good 

 coal measures, as the lighter coloured beds were full of the 

 rootlets of Stigmaria jicoides. 



The occurrence of coal measures at this place is of con- 

 siderable importance, as they were met with at a depth of only 

 115 yards from the surface, and if a good seam of coal could 

 be found the field is of tolerable extent, and, from its position, 

 would certainly command a first-rate market. The strata 

 which I examined afforded no evidence of what part of the 

 coal-field they belonged to; but, from the position of the 

 Pendleton seams on the north-east, and the Patricroft ones on 

 the west, they probably belong to the upper coal-field. The 

 most likely seam to be found is the Openshaw coal, formerly 

 worked near the Water Works Reservoir, in Beswick, near 

 Manchester, and occupying a geological position near to the 

 Slack Lane coal, formerly worked by Messrs. Lancaster at 

 Monton. 



Astley Section. 



At pages 235 and 268 of my former paper, I gave par- 

 ticulars of a bore hole made by G. P. Ken worthy, Esq., in 

 a field called the Horse Pasture, in Astley. In the upper 

 permian beds there, fifty -five beds of limestone had been 

 met with in a distance of 230 feet 6 inches. Many of these 

 contained fossils of the genera Schizodus, Bakevellia, and 

 Tragos. By the kindness of my friend, H. Mere Ormerod, 

 Esq., I am enabled to add the following additional particulars, 

 which carry the section through the lower permian beds into 

 the coal measures.
